The role of relativity with respect to odd-frequency pairing has ramifications to other systems beyond the simple condensed matter model here. It is suspected that there exists a region of the quantum chromodynamic (QCD) phase diagram in which quarks form pairs in a condensate, which is known as color superconductivity [1]}. As we showed in this work, there exists a relationship between relativity and odd-frequency pairing, which implies that odd-frequency color Cooper pairs in principle should appear in the color superconducting state.
